What’s the safest flea treatment for dogs? A vet's guide
Find out how to choose the safest flea treatment for dogs with this in-depth guide
When it comes to choosing the safest flea treatment for dogs, you’ll want to pick a product that will provide effective flea protection but with as little risk to the health of your dog as possible.
Fleas are a serious nuisance to your dog, causing itching and all-around misery. But more than that, fleas carry dangerous and potentially fatal diseases and parasites. A flea infestation can be the culprit behind life-threatening cases of anemia and they can also transmit a disease called Bartonellosis. If that weren’t bad enough, they also spread tapeworms, a nasty intestinal parasite. And those fleas on your dog can even bite humans or transmit those diseases to you!
So how can you protect yourself and your best friend? The first step is selecting the best flea treatment for dogs that is both most effective and safest for your canine companion. Whether you're considering flea medicine v collars or topical flea treatment vs oral, fortunately, there are many safe and effective products that can prevent fleas available through your veterinarian.
Choosing the safest flea treatment for dogs
To choose the safest flea treatment for dogs, you’ll first need to consider the type of flea treatment that best fits your dog’s needs and lifestyle. Flea treatments are available as collars, oral tablets or chews, and topical spot-on treatments. All three types of flea treatment categories have products that are safe and effective, but they each have their own pros and cons. You’ll also need to consider your dog’s age, health status, and the manufacturer’s recommendations before you pick a product.
We recommend always choosing a prescription product as recommended by your veterinarian, so you know you’ll be getting something that is safe and effective for your dog. Your veterinarian is also your best resource to help you pick a product that best fits your lifestyle and budget as well as your dog’s individual needs.
Types of flea treatment for your dog
Flea collars for your dog
Many pet owners prefer to use collars as their flea treatment because this method is easy and mess-free. Some of the modern flea collar products even last as long as 8 months, so you won’t have to remember to administer your dog’s flea treatment on a regular basis – a great plus for many busy families!
However, it is important to remember that not all flea collars are created equal. Many cheap over the counter flea collars are not safe or effective flea treatments and may not provide good protection against fleas. Before purchasing an over the counter product, be sure to research the best flea collars for dogs currently available on the market and check in with your veterinarian to see what they recommend.
Flea collars also have some drawbacks. Because they rely on medication which spreads from the collar across your pet’s skin, they are not a good option for pets who swim or bathe frequently, as this will wash away the medication and shorten the life of the collar.
Be sure to check the manufacturer’s recommendations to find out how often your pet can safely be exposed to water while using the flea collar. Collars also pose a choking hazard if your pet chews the collar or becomes caught on anything, such as a branch while running outside. Look for collars with a built in breakaway system to help minimize this risk, or consider another flea treatment option for pets that spend a lot of time outdoors.
Topical flea treatment for dogs
Topical flea treatments are often seen as a safe flea treatment for dogs because many types of this medication are not absorbed systemically, meaning they do not cross the dog’s skin barrier or get absorbed into the blood stream. This can be a safer option for dogs with a history of reactions to certain types of medications.
Topical flea treatments are typically applied every month or every three months, depending on the product, so pet owners need to be careful to remember to apply these products on time.
Like collars, these medications can be washed away if your pet swims or bathes frequently, so be sure to follow the manufacturer’s directions for use and consider an oral flea treatment if your pet is frequently exposed to water.
You’ll also need to be careful not to touch the area where the flea treatment was applied until it is fully dry, which usually takes about an hour after application. In rare cases, some dogs may have mild side effects such as local skin reactions at the site where the medication was applied, which may include hair loss, redness, itching, and scabbing.
Oral flea treatment for dogs
Oral flea treatments are easy to administer and typically offer one or three months of protection per dose. These flea treatment medications are usually flavored so most dogs actually enjoy taking them!
Many pet owners prefer this option because it is less messy compared to topical medication and does not wash away with swimming or bathing the way topical and collar flea treatments often do. These medications are safe and effective for most dogs, and side effects tend to be mild.
For dogs that do experience side effects, the most common symptoms are vomiting and diarrhea. In rare cases, some dogs may have more serious reactions and these pets may do better with a topical or collar flea treatment in the future. Pet owners will have to remember to give this medication every month or every 90 days, but because it’s easy to administer, most find it to be more appealing that topical medications.
The bottom line is that there are many safe and effective flea treatments available for your dog, and that is great news! You have many options to choose from depending on your lifestyle, budget, and personal preferences.
If you have questions about the best flea treatments for your dog, your veterinarian is an invaluable resource to provide product recommendations and guidance for you and your pup. Together, you and your veterinary team will undoubtedly find a safe and effective flea treatment that your whole family can feel comfortable with.
